**Problem Statement:**A flow field is defined by \( u = 2y \), \( v = xy \). Derive expressions for the \( x \) and \( y \) components of acceleration. Find the magnitude of the velocity and acceleration at the point (2,3). Specify units in terms of \( L \) and \( T \).**Solution:**1. **Velocity Components:** - The velocity components are given as: \[ u = 2y \] \[ v = xy \]2. **Acceleration Components:** - The \( x \) component of acceleration, \( a_x \), is given by: \[ a_x = \frac{du}{dt} = \frac{\partial u}{\partial t} + u \frac{\partial u}{\partial x} + v \frac{\partial u}{\partial y} \] Since \( u = 2y \), \(\frac{\partial u}{\partial x} = 0\) and \(\frac{\partial u}{\partial y} = 2\). - The \( y \) component of acceleration, \( a_y \), is given by: \[ a_y = \frac{dv}{dt} = \frac{\partial v}{\partial t} + u \frac{\partial v}{\partial x} + v \frac{\partial v}{\partial y} \] Since \( v = xy \), \(\frac{\partial v}{\partial x} = y\) and \(\frac{\partial v}{\partial y} = x\).3. **Calculate Specific Values:** - Evaluate both components of acceleration and the magnitude of velocity at the point (2,3). - **Magnitude of Velocity:** \[ \text{Velocity magnitude} = \sqrt{u^2 + v^2} \] - **Magnitude of Acceleration:** \[ \text{Acceleration magnitude} = \sqrt{a_x^2 + a_y^2} \]4. **Units:** - Velocity is measured in \( L/T \). - Acceleration is measured in \( L/T^2 \).By applying the given definitions and calculations, one can derive the necessary expressions for acceleration and determine the required magnitudes
